If we are going to migrate to another Zope release, now would be a good time. What advice would you give. Zope 2.6.1 would be the obvious choice although if Zope 2.7.X will be released soon it might be another possibility.
Any advice? hidden gotchas? release schedule intelligence?
Zope 2.6 series is good, esp. with regard to caching. But: I've had a few problems with moving old ZODBs (originating at 2.3 or so) to 2.6.1 from 2.5.1. If you're doing something similar, make sure that your testing of the new version really hits the server hard, or you won't expose the problem until you're live. Which is bad. If you do run into this, well, I don't know how to fix it yet. Someday I'll export/import everything to a new ZODB (possibly on DirectoryStorage) and see it that works. I expect it will. Also, some ZClasses have problems with the move, but that (and the solution) is well documented. On the list, at least. Other than that, I've found 2.6.1 to be a fine release. As to 2.7, well, I wouldn't anticipate it. Sure, it'll come out the day you deploy 2.6.1, but that's just how it goes. --jcc
